PostgreSQL Use Cases in SaaS
Multi-tenant data architecture
Customer relationship data
Usage analytics storage
Architecture Patterns for SaaS
Pattern 1
Schema-based multi-tenancy with shared tables
Pattern 2
Connection pooling for high concurrency
Pattern 3
Read replicas for analytics workloads
Performance
Proper indexing is key, use EXPLAIN ANALYZE, implement query caching with Redis, partition large tables, optimize vacuum and autovacuum settings.
Security
Use role-based access control, implement row-level security, encrypt data at rest and in transit, audit database access, use prepared statements.
Scaling
PostgreSQL scales well vertically. For read scaling, use read replicas. For write scaling, consider partitioning, Citus for distributed PostgreSQL, or PlanetScale/CockroachDB.
SaaS Compliance with PostgreSQL

Implementation Considerations

Success Story: PostgreSQL
Series A fintech with slow dashboard queries
Challenge
Dashboard queries taking 15+ seconds. Database becoming bottleneck as user base grew. No clear indexing strategy.
Solution
Fractional CTO audited schema and queries, implemented proper indexing, restructured problematic queries, set up monitoring.
Result
Average query time reduced from 8 seconds to 200ms. 97% reduction in database CPU usage. Dashboard now handles 10x more concurrent users.
